Basophils are indeed the least common type of white blood cells in the human body, making up less than 1% of the total white blood cell count. These cells play a crucial role in the body's immune response, particularly in the context of allergies and asthma. They contain granules filled with histamine and other mediators that contribute to inflammatory processes.

In contrast, lymphocytes are the most abundant type of white blood cells, involved in adaptive immunity; eosinophils primarily deal with parasitic infections and allergic reactions; and monocytes, which differentiate into macrophages and dendritic cells upon entering tissues, play significant roles in phagocytosis and presenting antigens to T cells. Thus, while all these white blood cells contribute importantly to the immune response, basophils are the least prevalent in circulation.
